Referring fmore specifically to the drawings, the numeral 10 indicates a spinning frame, having conventional features including an upper creel board 11 and central and lower boards 12 and 13, said boards supporting bobbins 15, the frame having top portion 16 adapted to'support a plurality of roll stands 17, having suitable drawing rolls therein through which the yarn is passed in the drawing operation.

The spinning frame has conventional thread boards 18 having eyes 19 therein for guiding the ends 20 from the bobbins through the drawing rolls to the bobbins 2l which bobbins have a ring rail 22 in association therewith, said bobbins being supported and driven on a spindle rail 23. The boards l1 and 12 are supported by suitable upright centrally disposed supports 24 on which collars 25 are mounted for supporting the boards, and the base of said supports 24 is secured in a suitable collar 27.

For the purpose of blowing lint and other particles from the above described apparatus, I mount longitudinally on the machine a plurality of perforated pipes 30, 31, 32, 33, 3,4 and on one side of the machine, and on the other side of the machine, similar perforated pipes 30a, 31a, 32a, 33a, 34a and 35a are similarly disposed.

Pipes 30 and 30a are suitably supported above section taken along the top creel board 11 by means of brackets 36 and 36a while brackets 37 and 37a which normally support the guide rods are employed for the perforated pipes 31 and 31a respectively, which replace such usual guide rods and perform their function. To board 12, I secure brackets 39 and 39a respectively which support pipes 32 and 32a. Pipes 3 3 and33a are supported by brackets or in a specially made collar which is similar to' the conventional collar heretofore employed exceptY that it has two longitudinally disposed cavities on the upper surface thereof in which pipes 33 and 33a are supported. Pipes 34 and 34a are supported beneath the thread board by any suitable means such as brackets and f 40a; whereas, no means are shown for supporting pipes 35 and 35a as it is evident that any suitable means may be employed for supporting these pipes.

While I have enumerated the various pipes and their location with respect to the conventional parts of a spinning frame, it is evident that I do not desire to be limited to the particular location or to the particular number of pipes, as any suitable number may be employed and may be disposed at locations which are found to be most efficient in operation.

The arrows in Figure 1 indicate the direction of flow of the jets of air against the parts of the machine.

In Figure 19, I show a perforation 42 which is adapted to direct the air in pipes 30 and 30a, for example, against vthe creel board 11, as indicated by the arrows and, of course, after striking against the creel board, the air will be deflected along the surface of the creel board, Where it spreads fanwise as the distance from the orifice increases. In the case of pipes 33 and 33a, the jets of air in one pipe will go toward the other pipe, but may be in staggered relation as shown in Figure 18 and will direct the air angularly downwardly. The staggered position of perforations may or may not be employed under certain conditions.

These downwardly and laterally directed jets of air are disposed at an angle and strike beneath the companion pipe and spread out as above described. In Figure 21 the direction of jets is shown diagrammatically. It is to be noted of this latter pair of pipes that their jets overlap transversely of the machine, so that areas between the pipes are also cleaned.

In the case of pipes 32 and 32a and possibly in case of others such as pipes 34 and-34a, there may be two rows of jets if desired as shown in Figure 20 for directing the jets of air against two or'more portions of the machine.

In case of pipes 35 and 35a, the jets of air may be directed toward each other in staggered relation as shown in Figure 18 against the floor for removing lint from beneath the machine, or the staggered relation may not be used.

Suitable means are employed for allowing compressed air to flow into the perforated pipes, and in Figure 2, there is 4shown one means of accomplishing this result. Pipes 30 and y31 are tapped into the pipe 45 which leads to a manifold 46, but pipe 32 leads directly to the manifold as lso socavar compressed air 50. Pipe 47a, is shown as leading from another portion of the distributing valve to the' manifold corresponding to d5, but serving pipes a to 35aJ inclusive (see Figures 5 and 5L Distributing valve mechanism comprises el casing 51 to which is secured a plate 52 by any suitable means such as stud bolts 53, said plates having a central projection 54 serving as a bearn ing for a rotatable disk 55 which has a circular raised portion 56 covering ports 57 and 53 for pipes li7 and li7a respectively. This disk has a port 59 therein' through which compressed air in chamber may pass when port 59 coincides with port 58 or port 57 as the case may be.

Disk is slidably mounted on a key. 60, this key being set in shaft 6l, which shaft 6l extends into, a projection 63 on disk 55 which projection extends into a cavity in projection 5d for rotative movement therein. If desired, ports 57 and 58 may be in the form of a slot, and if desired ports 59 may be also in the form of a slot, said form being indicated by reference character 6i in Figure 5.

Casing 51 has a projection 60 thereon in which is rotatably mounted shaft 6l, and a compression spring 67 surrounds shaft (il, between the inside of casing 5l and projection 68` on disk 55,

to force disk 55 against cover 52 when the device is inoperative as it is evident that the compressed air in itself would hold disk 55 against cover plate 52 when in operation, but by providing this spring it causes the ports 57 and 5ft to be closed when compressed air ,is iirst admitted to the cavity 50. l

Projection 66 has a packingv box 70 therein h1 which suitable packing may be placed, and a packing gland 7l is threadably secured on the interior of projection 66 with shaft 6l being rou tatably mounted in said packing gland and in casing 5l, and projecting to the exterior thereof, and in close proximity to packing gland 7l, and rixedly secured to shaft 6l is a ratchet wheel 73 which has a guard 74; which is adjustably mounted around projection 66 and packing gland 71 and is held in adjusted position by means, of a set screw 75. The guard portion extends over the periphery of ratchet wheel '73 for limiting the amount of rotative movement which is imparted to-said ratchet wheel by a lever 77 which is losely secured on shaft 6l and connned there on by means of a nut 70.

Lever 77 has a pawl 80 which is pivotally mounted on bolt 81. Said pawl 80 has a weighted portion 82 for holding the other end of pawl "50 in engagement with the teeth. of ratchet wheel or against guard 7d. oscillatory movement may be imparted to lever 77 by any suitable means such as a cam 83 secured on one of the gears in the railway head of the spinning frame so that an oscillation will be imparted to the shaft, and after the paw180 rides over guard 7d, it will en= gage teeth of ratchet wheel 73 and move shaft 61 and disk 55 thereon.

It is seen by the arrangement described thatV when port 59 registers with port `5b that compressed air will be admitted to pipe 47o and corne pressed airwill be admitted to a manifold similar to manifold 46 which will allow compressed air to pass simultaneously through pipes 30a to 35a inclusive and strike against a plurality of portions on one side of a machine, and then when port 59 travels to a point where it will coincide with port 57, compressed air will be passed into pipe 47, and into manifold 46 and out through all of pipes 30 toy 35 inclusiveto cause jets of air to strike against a plurality of portions along the other side of the machine.

The above described operation for a spinning frame may be carried out on any other type of machinery such as warping machines, roving frames, dy frames, and all kinds ci drawing, spinning, and winding machinery, and in fact any type of machine on which loose particles may collect and for which vthis system of per-= forated pipes might be applicable for removing these loose particles therefrom."

1n Figure 3, I have shown how the invention may be applied to a warping machine, which warping machine is indicated by reference character 00, with bobbins 9i 'and 92 'from which the thread is drawn through combs 93 and 94 in conjunction with suitable rol/ls and' thru drop "wires 100e and Morand woun'don warping beam 95. In this application, I'show perforated pipes 05 and 07 for comb 05, the direction of jets of air being indicated in dotted lines and I also provide pipes 95 and 90 for comb 9i with the jets of air being indicated as to direction. It is evident that additional perforated pipes may be applied to this type of machine if desired, an example being, perforated pipes s and 1005 for directing jets of air against the drop Wires 100i either simultaneously or alternately, and perforated pipes 100e and 100s! for directing jets of air against drop 'wires 100e. These jets oi compressed air will also keep clean the other parts of the machine cooperating with the drop wires, particularly the stop motion mechanism. It is also evident that pipes such as 100e, 1001), 100e and 100d may be installed on looms and all other machines having drop wires on yarns.

lin Figure i, 1 show another form of distributing valve for supplying lcompressed airy to the systems` oi pipes heretofore described in which the valve casing is indicated by reference character 100, which casing has a cover plate l10i secured thereto by any suitable means such as stud` bolts 102.

Cover plate 10i has a circular hole 115 therein in projection 107 which is covercclby a nut 103 which, likewise, has a circular centrally disposed hole therein, and this nut has an exterior cavity which is interiorly threaded for the reception of a packing gland 104, vand in which a shaft is rotatably mounted which shaft has 'one end thereof flxedly secured in a rotating valve member lot. Nut 103 is threadedly secured on pro- `jection 107 of cover' plater 101, and this nut 103 has the extension 108 thereon on which is mount-H` ed for oscillation lever 109 which lever is adapted to be oscillated by any 'suitablel mechanism such as that shown for oscillating lever 7'? in Figure 5. This lever has a bolt' lil) therethrough on which is pivotally mounted' afweighted pawl lll similar to pawl 80 in Figure 5. AThis pawl 111 is adapted to engage ratchet wheel 112 which is iixedly `secured on shaft 105 by any suitable means such as having the portion of shaft 105 which penetrates ratchet wheel 112 of smaller cross sectional area than the remaining portion of the shaft with a `nut 113 threadably securedon the end of the shaft for holding the ratchet Wheel in position. A compression spring 114i surrounds shaftl05 and is disposed in the cavity 115 inprojection' 107, and one end of this spring rests against the interior surface of nut 103; Whereas, the other end presses against rvalve 106 for seating the same against theseat 117 in casing 100. Casing 100 has a'supply pipe i9` in one side thereof leading to a cavity 118, and

lili

its

les

of pipe 49 two ports 120 and 121 in which pipes 122 and 123 are secured, one of said pipes being adapted to be led to one set of perforated pipes on a machine, and the other pipe being adapted to be ledto another set of pipes located in another portion of the machine, similar to the showing in Figures 1 and 2.

Valve 106 has passageways 125 and 1261 therethrough, these passageways being in different vertical planes in the valve 106 and being angularly disposed to each other, passageway 125 rbeing adapted to allow compressed air to flow from supply pipe 49 into pipe 123; whereas, passageway 126 isadapted to allow compressed air to flow from supply pipe 49 into pipe 122 as valve 106 is rotated. Valve 106 has in the other side thereof from shaft 105, another shaft -128 xedly secured therein which penetrates the closed end of casing 100 in which itis rotatably mounted.

In Figure 12 there is shown means whereby the compressed air can be cut off from the valve mechanism when the machine is in inoperative position, and in this view a portion of the end of a spinning frame is shown in which main drive shaft 130 has va loose pulley 131 thereon and a tight pulley 132 with a slidable'rod 133, which is connected to the shipper lever, not shown, of the machine. This rod 133 has a guide 134 fixedly secured thereto with an enlarged opening 135 therein through which belt 136, for driving the machine, passes after passing around pulley 131 or 132 as'the case may be and going to a suitable source of driving power, not shown.

Connected to rod 133 is an arm 137 to which is connected a link 138 which is connected with a sliding valve, the details of which are not shown, but the casing is indicated by reference character 139. To one side of valve 139 supply pipe 140 is connected, and from the other side of valve 139, pipe 49 is led to the valve mechanism which is employed for distributing the compressed air to the perforated pipes on the machine. In the position shown. the belt is on the loose pulley, and the machine is inoperativerand, therefore, valve 139 is closed to prevent air from being conducted through pipe 49 into distributing valve, and, of course, it is evident that when the rod 133 is moved from this position to cause belt 136 to engage the tight pulley 132, then Valve 139 will be opened and compressed air .will be admitted to the distributing Valve'.

In Figures 9, 10 and 11, a form of sliding Valve is shown, which may be used under certain conditions for distributing the compressed ,air to the two systems of pipes. This valve mechanism is indicated broadly by reference character 141 and has a cavity 142 therein, `the casingin which 142 occurs being indicated by reference character 143 which casing has a cover plate 144 thereon secured by any suitable means such as stud bolts 145. At one end of kcasing 143 a projection 146 occurs in which a passageway 147 is provided with two inlets thereto incase two should be needed and in the drawings, one of these inlets is shown closed by a plug-148 and the other inlet has connected thereto the supply pipe 49.

In the Abottom of casing 143 are ports 150 and 151 in which` pipes152and 153 are secured, said'V pipes being adapted to conduct compressedair to two different portions of the machine such as the two manifolds 46 in Figure 2, or if desired, to the piping arrangement shown in Figure 17.

Slidably mounted in the bottom of the casing 143 and covering one port at a time is a plate member 155 which has two upwardly projecting spaced lugs 156 and 157 having vertically disposed alined slots 158 and 159 therein, said lugs forming a space 160 therebetween and in slots 158 and 159 is mounted a shaft 161 which has a collar 162 secured thereon between the lugs 156 and 157. Casing 143 has a projection 168 thereony thru which shaft 161 passes, said projection having a space 169 for the reception of packing which packing is conned in position by means of a packing glandv 170 threadably secured on the interior of projection 168 and surrounding shaft 161 and forming a bearing portion for said shaft. Shaft 161 has collars 172 and 173 adjustably secured thereon on opposite sides of an arm 174 which arm is secured to a member 175, which is adapted to be reciprocated by any suitable means as by the traverse rail of a roving or spinningv framef for moving plate 155 back and forth to cover alternately ports 150 and 151.

In Figures 13 to 16 inclusive, another form of sliding valve is shown, which is very similar to the valve just described, except that manifolds are provided in the casing of the Valve instead of leading pipes therefrom to separated manifolds.

In the modified form shown in Figures 13 to 16 inclusive, a casing is indicated by reference character 180 which casing has manifolds 181 and 182 in the lower portion thereof to which respectively occur ports 183, 184, 185, 186 and ports 187, 188, 189 and 190, manifold 181 having in the upper portion thereof communication with valve chamber 191 by means of a port 192, whereas, manifold 182 has communication with chamber 191 by means of a port 193. A sliding .valve member 194 is mounted in chamber 191, said Valve 194 having upwardly projecting spaced members 195 and 196, having alined slots vertically disposed therein in which rod 197 is mounted by means of a collar 198 xed on said rod between the projections 195 and 196. This rod projects out of said casing through projection 199 having a packing chamber 200 therein and a packing gland 201 secured to projecticn 199 by any suitable means such as by threading or by stud bolts 202, this packing gland forming a bearing portion for shaft 197.

Casing 180 has two ports 203 and 204 leading from opposite sides into-chamber 191, one of these ports being adapted to have connected thereto'a source of compressed air and the other of said ports may be plugged unless two separate sources of compressed air should be desired to be led thereto so that in case of failure of one source of compressed air, that another would be available for uninterrupted operation of the system. Casing 180 has a suitable cover 205 secured over the open end thereof by any suitable means such as stud bolts 206, and this casing has a port 210 therein to which may be connected another source of compressed air or it may be .plugged if desired.

Ports 183 to 186 may have mounted therein pipes for conducting a compressed fluid to selected portions of a machine, while other pipes may be secured in ports 187 to 190 and conducted to other portions of the machine.

Heretofore, the description has been limited trbuting valve or manifold. Pipe 220 has con- 15g lll nested thereto branches 222, 223 and 224, and pipe 221 has connected thereto pipes 225 and 226. These pipes 222 to 226 inclusive are led down between the rows A, B, C and D of the machines, and. pipe 222 has branches 227, 223 and 229 leading to one side of row A of the ma" chine, whereas, pipe 225 has pipes 230, 23l'and 232 leading to the other side of row A of the machine. Pipe 225 also has branches 233, 234 and f 235 leading to one side of row B oi the machine, Whereas pipe 223 has branches 236, 237 and 236 leading to the other side of rowT B of the machine..

Pipe 223 also has branches 239, l246 and 2411 leading to one side of row C of the machines, while pipe 226 has branches 242, 243, and 24e leading to the other side of row C of the machines. Pipe 226 has branches 24:5. 246, and 247 leading to one side of row D of the machines, and pipe 224iv and branches 243, 249 and 250 lead--2 ing to the other side of row D of the machines. Each of the branches from said pipes has a pluu rality of pipes 252 connected thereto which are disposed along various portions of the machines and oneform of the disposition of these pipes is shown in Figure 1.

By this arrangementit is seen that blasts of air will be passed through the perforated pipes running along selected portions of the machine on one side of the rows A, B, C and D by compressed air being admitted through pipe 220 and its branches, and then as the distributing vmve moves to allow compressed air to pass out of its other port, pipe 221 will be charged with compressed air and the other side of the rows of machines will receive the jets of compressed air for cleaning the same, and in this Way there will be no interference between the jets of air issuing from the pipes on one side of the machine against the jets issuing from pipes on the other side of the machine.

Heretofore, the explanation has been largely devoted to alternately treating opposite sides of a machine or portions of a machine with cornpressed air, while other portions of the machine would not be operated upon, and in the distributing valves heretofore described, only two ports have been shown for operating upon two sets of perforated pipes by allowing compressed air. to be passed to the two sets of perforated pipes. In case a machine should b e equipped with a piu-- rality of perforated pipes and the alternate application of compressed air should not be desired to be limited to two sets of pipes, it is evident that a great number of pipes can be passed to various portions of a machine for progressive operationI of the mechanism by allowing compressed air to enter, first one pipe and then another, and another and so on until the cycle has been completed,`and in order to provide for an installation of this kind, I have shown in Figures 7 and 8 a type of valve which may be used for this purpose.

In Figures 7 and 8 reference character 266 indicates a casing having a plurality of ports 261, 262, 263, 264, 265, 266, 267 and 268, and if desired, it is evident that this number of ports can be materially increased by a re-design of the casing 260, These pipes 261 to 268 inclusive may be led to various portions of a machine and connected to a system of perforated pipes for passing compressed air thereto. Casing 260 has a projection 276 thereon which is hollow and has a bearing 271 therein for the reception of a shaft 272 which shaft has a disk 273 xedly secured thereon by any suitable means such as a-pin 274 penetrating hub portion 275 of disk 273. Casing 260 is closed by a cover plate 276 secured thereto by. any suitable means such as stud bolts 277. Cover 276 has a hub portion 273 having a cavity 279 therein for the reception of suitable packing, and vin which cavity a packing land 280 is mounted and being secured in position by any suitable means such as stud bolts 28l, said packing gland in association with the opening in cover 276 forming a bearing for another portion of shaft 272. Shaft 272 is driven by any suitable means for imparting rotation to the same. A suitable inlet pipe 49 is connected to the casing 260 and has communication with a cavity 282. Plate 273 has a perforation 283 therein which may be an elongated slot or a round perforation as desired, and this perforation 283 progressively coincides with ports 285 in which the pipes 261 to 268 respectively are mounted so that it is seen that as plate 273 is rotated that pipes 261 to 263 will be progressively traversed and allow perforation 233 to coincide successively with the ports in which the pipes are mounted and cause compressed air to be passed through said pipes. Between hub 275 and inside surface of cover plate 276 a compression spring 269 is mounted loosely on shaft 272 which holds plate 273 against circular slot portion 259 on inside of casing 260.

In Figure 18 a diagrammatic view is shown in which pipes on opposite sides of a machine are shown, and the arrows 'i286 and 287 respectively show the direction of the jets of air issuing from the perforations, it being evident that where pipes on opposite sides of a machine have their perforations directed toward each other even though at a different angle, the perforations may be staggered to cause the jets of air to not interfere with each other and also to cause them to more thoroughly clean the entire machine.

In case. of alternate charging of opposed pipes,

the staggered perforations 42a and 42h may or may not be used, as the perforations can be disposed in any suitable manner.

It is evident that a jet of air issuing from a perforation will spread out fanwise and cover a much larger area than the size of the perforation. Also the perforations can have parallel sidewalls, as shown or can be varied as to the angula-rity of the sidewalls to suit different conditions.

In the drawings and specification, there has been set forth a preferred embodiment of the invention and although.y specic terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
